(0.2а+5)³=0.008а³+3*5*0.04а²+3*0.2а*25+125=0.008а³+0.6а²+15а+125

(4-0.5в)³=64-3*16*0.5в+3*4*0.25в²-0.125в³=64-24в+3в²-0.125в³

(0.6с-5)³=0.216с³-3*0.36с²*5+3*0.6с*25-125=0.216с³-5.4с²+45с-125

(1/2d-2)³=1/8d³-3*1/4d²*2+3*1/2d*4-8=1/8d³-1/5d²+6d-8

(1/3t+3)³=1/27t³+3*1/9t²*3+3*1/3t*9+27=1/27t³+t²+9t+27

(2-1/4k)³=8-3*4*1/4k+3*2*1/16k²-1/64k³=8-3k+3/8k²-1/64k³
